New Chainsaw v.2013.02.25, marks Game attribute 'Score' as editable, for use with DG 1.0 build 0167 or newer.  This change allows both Score and Rank to be edited by the user, either by editing cell values or defining an attribute formula.  Necessary because build 0167 prevents non-'editable' game attributes from having a formula.  Note that this version of Chainsaw should not be used with older versions of DG, because before 0167 the 'editable' attribute was used for editing cell values only.
